ATTORNEYS BUILDING CONSTRUCTION SYSTEM The present invention relates tobuilding construction and more particularly to a building constructionsystem having laminated or sandwich floor, wall, and ceiling panelsjoined together in a manner to cause the entire building to act as arigid structural unit.

Heretofore, buildings constructed of wood, such as residential,apartments, shops and the like, employed floor and ceiling joists withcross-bracing members therebetween and walls were formed with spacedstuds with spacing or bracing members therebetween. The erectionoperation for such a construction system was time-consuming and requiredconsiderable expensive labor for erection and after erection had beencompleted, it was necessary to provide finishing materials, such asplaster or wallboard, for interior surfaces of the walls and to enclosethe floor and ceiling joints to provide a finished appearance to thestructure. Exterior surfaces of the walls also required finishingmaterials, such as siding, masonry or the like, all of which requiredconsiderable'expensive labor for erection.

The principal objects of the present invention are: to provide a novelbuilding construction system having prefabricated components designedfor rapid and efficient construction wherein floor, wall, and ceilingpanels are standard size members and are laminated or sandwich membersdesigned for modular construction; to provide such a buildingconstruction system having tight joints between connected floor, wall,and ceiling panels and tight joints between floor and wall panels andbetween wall and ceiling panels; to provide such a building constructionsystem which provides floors having a comfortable resiliency and minimumdeflection; to provide such a building construction system wherein thejoints are nailed and glued and require no cover members, either forinterior or exterior joints and the joints and panels present a smoothsurface for receiving suitable standard or decorative finishes, such aspaint, paper, suitable carpeting or floor tile, ceiling tile, andexterior siding where desired; to provide such a building constructionsystem which has insulating qualities particularly for sound and heatand which is substantially fire resistant; to provide such a buildingconstruction system which is designed for rapid fabrication and erectionwith a minimum factory and field force per unit and which produces arigid structure wherein walls, floors, and ceilings are interconnectedwhereby the entire building acts as a structural unit with the wallmembers acting as structural webs; to provide such a buildingconstruction system adapted for single andmultiple story construction;and to provide such a building construction system which is simple andpractical in construction, strong and durable in use, inexpensive andeconomical to manufacture and erect, and otherwise well adapted for theproposed use.

Referring more in detail to the drawings:

The reference numeral 1 generally designates a building formed ofprefabricated components which are secured together to form an integralstructural unit formed of a plurality of connected walls, such as bottomwalls or floors, top walls or ceilings, and upright side and interiorwalls. In the illustrated structure, the walls include floor panels 2extending between and supported on spaced support members 3, such asfoundation walls, beams, and the like with upright wall panels 4 eachhaving one end edge portion thereof supported on the floor panels 2 andextending upwardly therefrom to support avplurality of ceiling panels 5on the other end edge portion.

The floor panels 2,'wall panels 4, and ceiling panels 5 areprefabricated of a standard size which is particularly adapted formodular construction, such as 4 feet wide by 8 feet long, and thesupport members 3 are spaced at 8 feet centers to thereby supportadjacent ends of the floor panels 2, as later described. The floor,wall, and ceiling panels 2, 4, and S are similar in construction andeach is of laminated or sandwich construction and includes a pair ofspaced generally parallel outer layers or face members 6 and 7, with aninsulating inner layer or core member 8 between and spacing apart theface members 6 and 7. It is preferable that the face members 6 and 7 beof a high quality material, such as exterior grade plywood, and it isdesirable that the core member 8 provide sound and heat insulatingqualities and that the core member 8 be of a tire resistant material,such as a rigid foamed plastic, for example, styrene or the like.

The floor, wall, and ceiling panels 2, 4, and 5 are equal in thicknessto a 2 X 4 inches, namely 3 inches, and the face members 6 and 7 are l Ainches thick plywood members and the core member is I A inches thickrigid synthetic resin foam having a density of 2 to 5 pounds per cubicfoot.

The floor, wall, and ceiling panels 2, 4, and 5 are each designed tointerfit with adjacent panels to form a continuous tight joint betweenadjacent panels which does not require a cover even for exteriorsurfaces. In the illustrated structure, one of the face members of eachof the panels has a tongue member 9 extending outwardly from oppositeside edges thereof and the side edges of the other face member of therespective panel has a groove therein with the grooves 10 being shapedto receive a tongue member 9 extending from the side edge of an adjacentpanel to thereby form a tight joint between the respective face membersof the adjacent panels.

Additional structural continuity between respective adjacent floor,wall, and ceiling panels 2, 4, and 5 is provided by means for securingsame together including a spline member 11 at each joint with the splinemember 11 being positioned between the face members 6 and 7 of each ofthe adjacent panels and engageable with the core members 8 of each ofthe adjacent panels to be secured together. The spline member 11 and theedge portions of the core members 8 and face members 6 and 7 of theadjacent panels are coated with glue. Suitable fastening members, suchas nails or screws 12, are installed in the joint to extend through oneof the face members of each of the adjacent panels and through thespline member 1 1 and at least into the other face member of each of theadjacent panels to thereby provide a nailed and glued joint to securethe adjacent panels together in a tight joint having substantialstructural continuity. Floor panels are normally subjected to greaterloading than ceiling panels, therefore, the spline member 11 for thejoint between adjacent floor panels 2 is wider than the spline member Il for the adjacent ceiling panels 5. Spline members for floor joints arel 1% inches by 5 inches members and for ceiling joints are l /2 inchesby 3 5: inches mem-.

bers. The loading for wall panels 4 is less than that on floors andceilings, therefore, the joint between adjacent wall panels may havefewer fastening members 12 than the joint between adjacent floor andceiling panels 2 and 5 and the spline members for wall joints are lfiinches by 3 inches members. 7

It is desirable to provide a rigid connection between the lower end edgeportion of the wall panels 4 and the floor panels 2 to enable the wallpanels 4 to function as structural webs thereby enabling the entirebuilding 1 to function as an integrated structural unit, therefore, agroove or way 14 is provided in an upper face member of the respectivefloor panel 2 at the location of the respective wall. A spline member 15is received in the groove or way 14 and is positioned between the facemembers 6 and 7 of the wall panels 2 forming the respective wall.

It is preferable that the spline member 15 be continuous over the lengthof several wall panels 4 thereby increasing the continuity between thewall panels and the floor panels supporting same. Suitable fasteningmembers 16, such as nails or screws, are employed to secure the splinemember 15 to the respective floorpanel 2 and to the wall panels 4. Inthe illustrated structure, one group of the fastening members 16 extendthrough the spline member 15 and' into at least the face member of. therespective floor panel 2 having the groove or way 14 therein. A secondgroup of the fastening members wall panels 4 and through the splinemember 15 and- 16 also extend through each of the face members of theinto the other face member of the respective wall panel.

The rigidity of the joint and the structural continuity between thefloor and wall panels is increased by coat-" ing with a suitable gluethe groove or way 14, the spline member 15 and the end edge portions ofthe face'members and core member of the respective wall panels 4 whichengage the spline member 15 to thereby provide a nailed and glued jointhaving substantial structural continuity. v

The above described joint between wall panels 4 and floor panels 2 isalso employed for the joint between interior walls and ceiling panelsand for the joint between the exterior side walls of the building 1, andthe floor and ceiling panels.

Particularly for exterior side walls of the building 1, it is desirableto provide a suitable termite shield 17 between the support member 3 anda suitable plate 18 mounted thereon. It is also desirable to provide ametal flashing member 19 between the floor panel 2 and the wall panel 4and extending over a facia 20 covering the end of the floor panels 2 andthe plate 18 to thereby provide a finished appearance at the jointbetween the exterior side wall and the floor and supporting member.

The side edges of the floor panels 2 are parallel with the exterior endwalls of the building 1, therefore, it is necessary to remove the tonguemember 9 of the respective exterior side edge portion of the face memberof the floor panel 2 and it is preferable to glue the removed tonguemember 9 in the groove 10 of the other face member. A groove 21 isformed in the upper face member of the floor panels 2 adjacent theexterior edge thereof to receive a tongue 22 extending from a modifiedspline member 23 which is nailed and glued in the floor and wall panels,as previously described.

The joint between the wall panels 4 and the ceiling panels 5 is a mirrorimage of the corresponding joint between the wall panels 4 and the floorpanels 2, except at the end walls of the building 1 having gable panels24 extending upwardly above the ceiling panels 5 and in the illustratedstructure, an exterior face member 25 of the gable panel 24 extends overthe edge portion of the respective ceiling panel. The exterior facemember 25 has a way or groove 26 therein to receive the tongue member 9extending from the respective face member of the ceiling panel 5.

The wall panels 4 at the exterior corners of the building 1 are rigidlyjoined together to provide substantial residence against twisting due towind forces and the like. Exterior face members 27 of the wall panelsforming the exterior corners are moved into engagement and the interiorface members 28 of said wall panels each have an edge portion thereofremoved and the interior face members 28 are also moved into engagement.Spline members 29 arepositioned between the interior and exterior facemembers 27 and 28 of each of the wall panels and the spline members29-are in engagement. One group of suitable fastening members, such asnails or screws 30, secure each of the spline members 29 in therespective wall panel and an other group of the fastening members 30secure the wall panels to the spline member 29 in the other wall panel.

Opposite corners of the building 1 form similar pairs and in one of thepairs, the tongue member 9 extends from the exterior face members 27 andthe groove 10 is in the interior face members 28. The exposed tonguemember 9 is cut away from one exterior face member" 27 and a groove orway 31 is formed in the exterior face member 27 to receive the tonguemember 9 of the other exterior face member 27.

In the other of the pairs of similar exterior corners, the exterior facemembers 27 have the grooves 10 in the exposed edge thereof. The tonguemembers 9 are cut away from each of the removed portions of the interiorface members 28 and are secured in the grooves 10 of the exterior facemembers 27, preferably by gluing same in place.

T-shaped vertical joints between interior and exterior wall panels andbetween normal or perpendicular interior wall panels are similar andeach have a way or groove 32 formed in the face member to receive aspline member 33 between the face members of the wall panel abutting thewall panel having the groove therein. The spline member 33 is secured tothe face member of the wall panel having the groove or way 32 thereinand the spline member 33 may be secured to the face members of the otheror normal wall panel by suitable fastening members 34 and by gluing.

The building construction system is particularly adapted for multiplestory construction and FIG. 10 illustrates a joint between upper andlower exterior wall panels at an intermediate floor panel. Grooves orways 36 and 37 are formed in upper and lower face members, 38 and 39respectively, of the intermediate floor panel to receive spline members40 and 41 respectively. The spline members 40 and 41 are each secured inthe ways 36 and 37 and between the face members of the upper and lowerwall panels, as by nailing and gluing, as previously described. A faciamember 42 is secured in covering relation to the upper and lower wallpanels and to the end of the respective intermediate floor panel.

When a sloping'roof is desired for the building 1, such as along sidewalls thereof, a nailer 43 is secured on an upper side of the ceilingpanels along the side edges of the building 1. The nailer 43 is cut tothe desired slope and a suitable roof panel, such as a plywood panel 44is secured to the nailer 43 in a conventional manner and suitablesupport members 44 provide support for the panels 44 and a facia 45 issecured in position covering the edge of the ceiling panel and a splinemember 46 therein. The panels 44 are covered with a suitable roofingmaterial (not shown) to provide a finished structure.

Window and door framing is particularly easily installed at the factorywherein each framing member 47 has a way or groove 48 formed therein toreceive a spline member 49 which is glued in the way or groove 48 andsuitable fastening members, such as nails or screws 50, secure thespline member 49 to the face members of the respective wall panel.

The building construction system is particularly designed to permitplumbing and electrical conduits to be installed at the factory whereinthe plumbing and electrical conduits are positioned between the facemembers 6 and 7 of the respective panels. Suitable holes may be pre-cutor pre-drilled at selected positions in respective floor, wall, andceiling panels and in respective face members of the panels for variousfixtures, switches and the like.

The face members of the respective panels are particularly easy tofinish in any selected manner,'such as painting or decorative paper forexposed interior surfaces of walls and ceilings. Exposed interior floorsurfaces are particularly adapted to be painted, receive suitable floorcovering, such as asbestos or vinyl tile or carpeting. Exterior wallsurfaces may be painted or have a suitable siding applied thereto and amasonry veneer may also be applied over exterior wall surfaces.

However, it is noted that the tight joints formed at exterior cornersand at floor and ceiling panels, as previously described, do not requirecovers, such as battens, siding, masonry veneers, or the like.

It is to be understood that while l have illustrated and described oneform of my invention, it is not to be limited to this specific form orarrangement of parts herein described and shown. 7
